Executing SOAP services, which doesn't return value
---------------------------------------------------
Key: ODE-260
URL: https://issues.apache.org/jira/browse/ODE-260
Project: ODE
Issue Type: Bug
Components: BPEL Runtime
Affects Versions: 1.1.1, 1.1
Environment: Windows XP Pro, JDK 1.5.0.07, Oracle 10g XE, Apache
Tomcat 5.5.25, OpenJPA
Reporter: Alexey Ousov
Fix For: 1.2
Very strange things happen, when executing exetrnal services in two-way style,
and this service doesn't return values. Something like this:
<?xml version='1.0' encoding='utf-8'?>
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/";
xmlns:wsa="http://www.w3.org/2005/08/addressing";>
<soapenv:Header>
<wsa:Action>http://www.comped.it/te/dbService/dbService/commitTransactionResponse</wsa:Action>
<wsa:RelatesTo>uuid:hqejbhcnphr35voswr4cg3</wsa:RelatesTo>
</soapenv:Header>
<soapenv:Body />
</soapenv:Envelope>
First of all I got the following exception (happens only if INFO logging is
enabled):
16:30:19,859 ERROR ExternalService$4.call(333) : Unable to process response:

I fixed it, but then I've got the following (because element was empty string):
18:03:17,843 DEBUG LoggingErrorHandler.fatalError(89) : :-1:-1:FATAL:Premature
